No, I don't know who Ashley Greene is, either. This image comes off of the Celebrity Photos wire. It's an amazing shot, and it suggests a modesty you don't see very often. Given that the world is coming completely apart and that all of the decency has been sucked out of modern pop culture (see previous post), it's more than an antidote to see Miss Greene looking over her shoulder like this.
Movies stars used to look like this, or so I am told.
